Given that there's been no action, and no reply in 2.5 years, I think we just have to conclude that NXP don't care, and have no intention of doing anything about this.
I checked the link, and showed "out of service" on the web, Since the software can't be used, you can design your PCB antenna according to : http://www.nxp.com/documents/application_note/AN171530.pdf ( UHF RFID PCB antenna design ), and can also fill "feedback", then submit it to administrator.
